I believe these stories exist because we sometimes need to create unreal monsters and bogies to stand in for all the things we fear in our real lives: the parent who punches instead of kissing, the auto accident that takes a loved one, the cancer we one day discover living in our own bodies. If such terrible occurrences were acts of darkness, they might actually be easier to cope with. But instead of being dark, they have their own terrible brilliance. . . and none shine so bright as the acts of cruelty we sometimes perpetrate in our own families.
Because, as we know, almost anything can be read into any book if you are determined enough. This will be especially impressed on anyone who has written fantastic fiction. He will find reviewers, both favourable and hostile, reading into his stories all manner of allegorical meanings which he never intended. (Some of the allegories thus imposed on my own books have been so ingenious and interesting that I often wish I had thought of them myself.)
When a child comes in, I believe that it's a 'multipersonhood,' and it knows it, its consciousness knows it, and it has a nuclei in the center of its consciousness that is the repository of all experience and all knowledge. And when you look in the eyes of your baby and you feel this sense that they are an old soul, I believe indeed they are.
